Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a grouting sleeve anti-leakage mechanism. Background Art

[0002] Prefabricated concrete buildings refer to concrete structures that are designed and constructed mainly with factory-produced prefabricated reinforced concrete components and assembled on site. When assembling prefabricated reinforced concrete components, they are usually assembled into a whole through grouting sleeves.

[0003] There is an existing application number of 202120684654.6, and the patent name is a utility model patent for a grouting sleeve for an assembled concrete grouting connection point, which includes base surface concrete and precast concrete. The base surface concrete is provided with a first steel bar, and a grouting sleeve is provided at the lower end of the precast concrete. The upper end of the inner wall of the grouting sleeve is an inclined surface, and the upper end of the inclined surface is flush with the upper end of the inner wall of the grouting outlet. However, during grouting, the grouting machine pours concrete into the grouting sleeve through the grouting inlet, and the concrete liquid level in the grouting sleeve continues to rise. Under the action of the inclined surface, the concrete will be discharged directly from the grouting outlet. However, after separating the grouting pipe from the grouting inlet and blocking the grouting inlet with a plug, the concrete in the grouting sleeve will leak from the grouting inlet, affecting the grouting quality.
